To reduce the development of drug-resistant bacteria and maintain the effectiveness of Cefdinir and other antibacterial drugs, Cefdinir should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Cefdinir (cefdinir) capsules and Cefdinir (cefdinir) for oral suspension are indicated for the treatment of patients with mild to moderate infections caused by susceptible strains of the designated microorganisms in the conditions listed below.


The recommended dosage and duration of treatment for infections in adults and adolescents are described in the following chart; the total daily dose for all infections is 600 mg. Once-daily dosing for 10 days is as effective as BID dosing. Once-daily dosing has not been studied in pneumonia or skin infections; therefore, Cefdinir Capsules should be administered twice daily in these infections. Cefdinir Capsules may be taken without regard to meals


Overdose can cause nausea, vomiting, stomach pain, diarrhea, skin rash, drowsiness, and hyperactivity.


Store at room temperature between 20 and 25 degrees C (68 and 77 degrees F) away from moisture and heat. Throw away any unused medicine after the expiration date. Keep out of the reach of children.

MICs of six oral cephalosporins (cefdinir, cefpodoxime, cefaclor, cefuroxime, cefixime and Ro 40-6890), four quinolones (ciprofloxacin, ofloxacin, OPC-17116 and fleroxacin), desacetylcefotaxime, Ro 23-9424 (a fused combination of fleroxacin + desacetylcefotaxime) and RP 67829 (a benzonaphthyridine) were determined for 49 penicillin-susceptible (S), 38 penicillin-intermediate (I), and 83 penicillin-resistant (R) strains of Streptococcus pneumoniae. All MICs were determined by a standardized agar dilution method utilizing Mueller-Hinton agar supplemented with sheep blood. MIC90s of OPC-17116 and RP 67829 were < or = mg/L, and were unaffected by penicillin-susceptibility. MICs of all beta-lactams increased with increasing penicillin-MICs, with cefdinir, cefpodoxime, cefuroxime and Ro 40-6890 being the most active compounds, followed by cefaclor and cefixime. MIC90s of ciprofloxacin and ofloxacin were 2 mg/L. MIC90s of Ro 23-9424 were lower than those of either parent compound (fleroxacin 8 mg/mL for all three groups; desacetylcefotaxime 0.5 mg/mL [S], 0.5 mg/mL [I], 4 mg/mL [R]; Ro 23-9424 0.125 mg/L [S], 0.25 mg/L [I], 0.5 mg/L [R]). The results indicated that several newly introduced and experimental antimicrobials have potential for the treatment of infections caused by resistant strains of S. pneumoniae.

The aim of this work is to optimize a spectrofluorimetric method for the determination of cefdinir (CFN) using the Taguchi method. The proposed method is based on the oxidative coupling reaction of CFN and cerium(IV) sulfate. The quenching effect of CFN on the fluorescence of the produced cerous ions is measured at an emission wavelength (λ(em)) of 358 nm after excitation (λ(ex)) at 301 nm. The Taguchi orthogonal array L9 (3(4)) was designed to determine the optimum reaction conditions. The results were analyzed using the signal-to-noise (S/N) ratio and analysis of variance (ANOVA). The optimal experimental conditions obtained from this study were 1 mL of 0.2% MBTH, 0.4 mL of 0.25% Ce(IV), a reaction time of 10 min and methanol as the diluting solvent. The calibration plot displayed a good linear relationship over a range of 0.5-10.0 µg/mL. The proposed method was successfully applied to the determination of CFN in bulk powder and pharmaceutical dosage forms. The results are in good agreement with those obtained using the comparison method. Finally, the Taguchi method provided a systematic and efficient methodology for this optimization, with considerably less effort than would be required for other optimizations techniques.

Twenty subjects were randomized to receive placebo or cefdinir for 30 days for the treatment of recent-onset OCD and/or tics. The placebo group received a comparable inactive treatment matched for taste, color, and consistency. The Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) and Yale Global Tic Severity Scale (YGTSS) were the primary outcome measures utilized.

Three new, orally administered cephalosporins (BK-218, cefdinir, RU29246) were tested against 13 representative strains of Legionella. Cefdinir was most active [50% minimum inhibitory concentration (MIC50), 1 micrograms/ml], a potency comparable to the reference drug cefixime and eightfold less active than erythromycin. BK-218 was the least active cephalosporin (MIC50, 8 micrograms/ml) or 100-fold less potent than rifampin. These investigational cephems appear poorly suited by activity assays for Legionellosis therapy.

cefdinir class of antibiotics

One hundred and fifty-one patients completed the study. Clinical and bacteriological efficacy of cefditoren pivoxil was comparable to that of cefdinir in the treatment of uSSSI. One hundred and five patients were eligible for per protocol (PP) analysis of bacteriological outcome and clinical efficacy. Clinical cure or improvement was achieved in 98.00% patients treated with cefditoren pivoxil and 98.18% patients treated with cefdinir. In the modified Intent to Treat (mITT) patient population, clinical cure or improvement was recorded in 97.33% patients treated with cefditoren pivoxil and 96.20% patients treated with cefdinir. Microbiological eradication (or presumed eradication) was recorded in 88.00% patients treated with cefditoren pivoxil and 94.55% patients treated with cefdinir. The above differences in the outcome rates between the two drugs were not statistically significant. Six adverse events (AEs) (two in cefditoren group and four in cefdinir group) were reported in this study.

A simple, fast, specific, stability-indicating, and precise reversed-phase liquid chromatographic method was developed for the determination of Cefdinir in its different dosage forms, i.e., capsules and suspensions. The method was developed and optimized by analyzing the placebo preparation, formulations, and degraded samples of the drug substance according to the International Conference on Harmonization. The proposed method can successfully separate the drug from degradation products formed under stress conditions along with pharmaceutical ingredients such as preservatives. The Azomax Azithromycin 250 Mg developed method was used successfully to determine Cefdinir in capsules and Insta-use suspensions. The developed method was found to be linear for a concentration range of 6-14 microg/mL. Average recoveries obtained with the method were 99.3 +/- 0.4 and 99.6 +/- 0.4% for Insta-use suspensions and capsules, respectively. The method was shown to be specific, precise, and robust.

A short history of the pharmaceutical science and technology, postwar 50 years is divided into nine sections for the purpose of discussion. 1. Japan's postwar rehabilitation, Japanese pharmaceutical industries and newly developed pharmaceutical sciences and technologies. In 1945, the Japanese pharmaceutical industry was reconstructed. Production of penicillin was carried out with the strong support of the U.S. Occupation Forces. New sciences in pharmacy (biochemistry, biopharmacy, pharmacology, microbiology, physical chemistry, etc.) were introduced in this period. 2. Introduction age of foreign new drugs and technology (1951 to 1960s). Japan gained independence in 1951. Japanese pharmaceutical companies imported many new drugs and new pharmaceutical technologies from the U.S.A. and European countries in this period. Then, these companies were reconstruction rapidly. However, consequently Japanese pharmaceutical companies were formed as an imitation industry. 3. Rapid economic growth period for pharmaceutical companies (1956 to 1970s). In this period, many Japanese pharmaceutical companies grew rapidly at an annual rate of 15-20% over a period of 15 years, especially with regard to the production of active vitamin B1 analog drugs and some OTC (public health drugs). Some major companies made large profits, which were used to construct research facilities. 4. Problems for the harmful effects of medicines and its ethical responsibility. In the 1970s, many public toxic and harmful effects of medicines were caused, especially SMON's disease. In this time, many pharmaceutical companies changed to its security got development of ethical drugs. 5. Self development of new drugs and administration of pharmaceutical rules (1970s). During the 1970s, many pharmaceutical laws (GLP, GCP, GMP, GPMSP etc.) were enacted by the Ministry of Health and Welfare. In 1976, the Japanese Pharmaceutical Affairs Law was revised, which set forth standards regarding the efficacy and safety of ethical drugs Amoxi Dog Medicine and re-evaluation of drugs. Many facilities were built for the purpose of ensuring efficacy and safety, as shwon in Table 1. 6. Problems of Intellectual Property and followed the revisionist line of research and development for new ethical drugs. In 1976, Japanese pharmaceutical companies ceased to be an imitation industry, and increased research for the development of new drugs. 7. Pharmaceutical science and technology innovation (After 1985). Many of the pharmaceutical innovations during this period were as follows: 7.1) Technology innovation for evaluation of drug efficacy; 7.2) 1st to 3rd medical diagnostic technology innovations; 7.3) medical analytical methods and spectrometry technologies; 7.4) Computer-aided drug-design technology and drug information technology innovation; and 7.5) Drug delivery system and treatment drugs. 8. Recent research and development of new ethical drugs in Japan (1970 to 1995). Cephalosporine type beta-lactams (cefazolin, cefametazole, furomoxef, cefdinir), new quinolones (norfloxcin, ofloxacin, tosfloxcin), H1-Blockers (famotidine), Ca-antagonists (diltiazem, nicardipine), and other new drugs (pravastatine, taclolimus, leuprine) etc. came onto the market. 9. International Harmonization Age and Review toward 21 century. The rapid development and globalization of the pharmaceutical market has promoted international harmonization and rationalization of pharmaceutical regulatory affairs. In 1990, the Japan Pharmaceutical Manufacturers Association published a report toward 21 century, which described practical plans.

A total of 2751 patients were enrolled (age <13 years, n = 1274; age > or =13 years, n = 1477). Patients were randomized to receive cefdinir once daily (n = 569) or twice daily (n = 1086) for 5 or 10 days, or penicillin 4 times daily (n = 1096) for 10 days. Of the 2751 patients enrolled, 2198 were evaluable for clinical and microbiologic outcomes. Compared with the 10-day penicillin regimens, the cefdinir regimens for 5 or 10 days produced higher clinical cure and microbiologic eradication rates. Combined clinical cure rates were significantly higher for cefdinir compared with penicillin (94% vs 83%, respectively; P < 0.001). Combined microbiologic eradication rates were also significantly higher for cefdinir compared with penicillin (92% vs 77%; P < 0.001). Both cefdinir and penicillin were well tolerated, as >98% of patients completed the course of therapy.

A total of 1011 healthy subjects were randomly assigned to 1 of 2 treatment-order groups; 965 were evaluable for the taste and smell analyses. Baseline demographics of evaluable subjects were similar among test groups. Approximately even proportions of participants were female or male (50.1 % vs 49.9%), most (84.1%) were white, and slightly more participants were aged 7 or 8 years rather than younger (age 4 years, 16.0%; age 5 years, 17.4%; age 6 years, 18.7%; age 7 years, 23.2%; age 8 years, 24.8%). Of the 965 children who tasted both antibiotic suspensions and determined their preference, 798 (82.7%) rated the taste of cefdinir as really good or good (the highest possible ratings); 712 (73.8%) assigned the same ratings to amoxicillin/clavulanate potassium, cefprozil, azithromycin, or generic amoxicillin (P < or = 0.001). With regard to smell, 671 (69.5%) rated the smell of cefdinir as really good or good; 636 (65.9%) assigned these same ratings to the comparator agents (P = NS).
